An ineluctable story of what it takes to roam between the stars.

are we losing out?

I thoroughly enjoy standing next to Luke Skywalker on Tatooine, watching the twin suns set—two sunsets for the price of one, and twice the inspiration for dramatic life decisions. Then I follow him into hyperspace, where we cross hundreds of lightyears in a matter of hours and arrive right on time for the next thrilling backdrop, big revelation, or heroic sprint down a corridor.

From Star Trek and Star Wars to Dark Matter, most space operas take a very creative approach to the universe’s speed limit: the vacuum speed of light. If we insisted on obeying it, the Star Wars saga would unfold over roughly 50,000 years. It would still be epic—just with considerably more waiting, and a much larger role for historians.

what is there to gain?

Space operas that do respect the speed limit are often remarkably rich. Think the Alien franchise, Becky Chambers’ To Be Taught, If Fortunate, James S. A. Corey’s Leviathan Wakes, or Arthur C. Clarke’s classic Space Odyssey. (Though in the latter two, the protagonists don’t even try to leave the solar system—perhaps wisely saving themselves from a very long commute.)

So where does storytelling take us if we accept this universal truth? What new kinds of adventures appear when distance and time refuse to be hand-waved away? Imagination is the last frontier. “Engage.”

it begins here…

It is the slow speed of light that confines cultures like ours to their home planets. Let’s explore what that really means—and what it actually takes to travel between stars. Who are the true interstellar spacefarers?

Because what begins with simple observations soon leads to profound questions about immortality, identity, and the future of human life on Earth itself.

I hope you’ll follow my blog or podcast, which explores the roots of an ineluctable story—the story of the next step of evolution.

about me

K. A. Langfeld is a Professor of Theoretical Physics and the author of Kindred of Old, a speculative science-fiction universe shaped by the deepest questions of modern physics: time, light, mortality, identity, and the future of humankind.

Born from a lifelong fascination with space and time, Langfeld’s fiction draws on the scientific reality that the flow of time is not universal but personal. His professional life is spent with mathematics, high-performance computing, and the hidden structures of nature; his creative life asks what those structures might mean for human beings who dream of crossing the stars.

The Kindred of Old trilogy begins with First Light Rising, the story of Tom, a young man whose failure to age draws the attention of governments and threatens to set the world on fire. As humanity confronts the terrifying promise of immortality, the story expands from Earth to interstellar space, from political crisis to evolutionary mystery, and from one life to the possibility of a much older, stranger family among the stars.

Langfeld’s science-fiction approach resists easy shortcuts. Instead of ignoring the speed of light, his work embraces it, asking what kinds of beings could truly become interstellar travellers when distance and time refuse to be wished away. The result is a blend of hard science, philosophical speculation, and emotional storytelling: a universe where immortality is not merely a gift, but a burden, a responsibility, and perhaps the next step in evolution.

Writing as K. A. Langfeld, he lives between England and Sydney, Australia, and continues to explore the boundary where science ends, imagination begins, and the oldest light in the universe still has something new to reveal.
